I don’t have any problems with this approach. Considering the very low cost of monitors today, I think it’s a solution everyone should consider.
If you are happy with your “solution” great but to my way of thinking this is not a solution…it is at best a workaround.
I already have 2 monitors, but I want my plugs to open on the mixer screen not the arrange page as when I’m mixing this is where my main focus is.
